ALARM-CLOCK.

SPECIFICATION forming part of Letters Patent No. 307,022, dated October 21, 1884.

Application filed February 7, 1884. (No model.)

To all whom, it may concern:

Be it known that I, WALTER D. DAVIES, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new 5 and useful Improvement in Alarm-Glocks, of

which the following is a specification.

My invention relates particularly to small clocks having cases which are now commonly made of metal, and of circular or nearly cirr cula-r form, and which have an alarm-bell on the top of and external to the case, the axis of the bell usually being vertical.

As heretofore made alarmclocks of the kind above described have had the alarmr movement within the case, and the alarm-h ammer has been extended upward through an opening in the top of the case and into the bell. The size of the clock-case is necessarily increased by the arrangement of the alarmmovement therein; and the object of my invention is to make the clock-case as small as possible, or, in other words, to provide an alarm-clock having the bell arranged as above described, and the case of which shall be no larger than the smallest clock without an alarm.

In carrying out my invention I arrange the whole alarm mechanism, including the alarmhammer, 011 the exterior of the case and entirely within the aiarnrbell, at the top thereof, the alarm-movement being arranged horizontally, so that the alarm-hammer will have movement in an approximately horizontal plane, and will operate on the interior of the 3 5 bell. I also arrange or employ a trip-lever to be operated by the timemovement of the clock, and which is extended upward through an opening in the top of the clock-case, and serves to directly block the alarm-hammer.

My invention consists in novel combinations oiparts,hercinafter described, and pointed out in. the claims.

In the accompanying drawings, Figure 1 is a partly-sectional front view of a clock embodying my invention. Fig. 2 is a plan thereof, the bell being removed; and Fig. 3 is a sectional view of an alarm-bell and a part of the alarm-movement arranged therein, illustrating a modification of my invention.

Similar letters of reference designate corre sponding parts in all the figures.

A designates the clock-case, which may be of any suitable construction and material. Usually the case will be of sheet metal, and

will consist of a cylindric or polygonal body,

in the front of which is the dial B and at the back of which is a removable disk or head.

a b designate the hands, and c designates the alarm-index, which may be set by turning it on the dial to any predetermined hour. 6 By turning the index 0 the alarm-cam will be adjusted or moved to release the trip-lever O at the desired time.

The alarm-trip forms no part of my invention, and may be of any suitable or well-known 6 5 character which will release the trip-lever at the desired time. The trip-lever 0 projects or extends upward through an opening, (I, in

the body of the case A, as shown in Figs. 1

and 2. On the exterior of the case, and, as here shown,on the top thereof, is a projection, e, on which rests the lower plate, f, of the alarm-movement. The upper and lower plates, ff, are rigidly connected by posts 1, and by means of screws 6 the frame of the alarmmovement is secured on the exterior of the case.

On the upper plate, f, of the alarm-movement is formed or attached a hub or stem, f,

which is or may be screw-threaded, and on which the bell D is secured. Through the stem f passes the winding-arbor f of the alarm-moven1ent. The stem f may terminate at the top of the bell D, as shown in Fig. 1, and the arbor f may be prolonged considerably above the said stem and have the pondant E screwed upon it; or the said stem f may be prolonged above the bell, as shown in Fig. 8, and have the pendant E screwed upon it. In the latter case the arbor f" will be pro- 0 longed above the stem f 3 and into the pendantring, and will have a head, 1 secured upon it.

In Fig. 1 the arbor f is to be turned by turning the pendant E itself; but in Fig. 3 the V said arbor is turned by the head ,like a stem- 5 winding watch.

g designates the actuating spring of the alarm-movement, and g designates the alarmhammer, which is operated by the alarm-es capement, of which g designate the escaperoo wheel and anchor. The hammer g is blocked by the trip-lever C, before dcscribed,and when said lever is released the hammer operates on the hell 1) in a well-umlerstood manner. The bell D has an approximately vertical axis, and the entire alarm movement, including the alarm-hammer 5 is arranged within the bell, the hammer being arranged to operate on the interior of the bell and in an approximately horizontal plane. 'lhetriplever C also serves to block the hammer directly. The winding-arborf of the alarm-movement not only extends through the stem f,but has an amply long bearing formed therein, as shown most clearly in Fig. 3.

13y arranging the entire alarm mechanism or movement external to the ease and within the bell D, I am enabled to make the case A smaller than would otherwise be possible, and the whole produces a very ornamental alarm clock, which is small and may be sold at a small price.

The invention is applicable to one and eight day clocks.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a clock-case and the alarm-bell D, having an approximately vertical axis, and secured to a fixed support on the top of the case, of an alarm-movement arranged on the top of the ease within the said bell, and having its hammer, 1 movable in a horizontal plane, and its windingarbor, 1", extending through the fixed support of the bell and projecting above the bell, to allord provision for turning it, and a trip-lever, 0, extending upward through an opening in the case and serving to bloc]; the ahu'nrhammer, substantially as and for the purpose described.

2. The combination, with a clock-case having an upward external projection, c, of an and serving to directly block said hammer, 1

and an alarm-bell, D, containing and inclosing within it said alarm movement and hammer and supported by said movement, substantially as herein described.

.1:. The combination ol'thecase A,thcalarmmovement secured. thereon, having the ham- 11'1erg,movablc in a horizontal plane, and having on its upper plate, f, the stem f, the winding-arborf, passing through and having a bearing in said stem, and the alarm-bell I), su1J ported on said stem and inclosing within it the alarm-movement with its alarnrhammer, substantially as and for the purpose herein described.

The combination of the case A,the alarmmovement secured thereon, and having on its upper plate,f, the stem f, the bell l), con taining the said alarm-movement and supported by the said stemf, the pendant Illalso secured upon the said stem, and the windingarborj",extending through said stem into the pendant-ring, substantially as herein described.
